14:10 you've reinvented the Theremin!

That has got to be the cleanest inside of an old valve radio. Is very satisfying to watch these videos, not forgetting the entertaining side commentary.

In place of expensive plastic screwdrivers i use ground plastic knitting needles they work really well and you can get a whole bunch of them from a thrift store for a $1 great vid, thanks.

14:05 Nice little theremin effect with the antenna coil.

Interesting radio! Sold before radios were required to have an FM receiver within the production model if the output wattage was above .25 watts. Must have been sold about 1963-1968. 1969 was when the law of marketing AM band only radios was put into effect. (Done so to promote the development of the FM radio band. I know! I was there. Still have & use an AM band radio my mother gave me for Christmas 1967. I only had to repair it once. (Mom, RIP! I still love your gift to me after 50 years! Every morning it greets me with morning news while I shower, brush my teeth, take my daily medications, comb my hair & shave!)

"It's like lo-Fi punk rock radio" Awesome!

Nice repair! This is the 1st time I've heard of mica disease.

At 16:05 you say "I could listen to this all day long" That just made my day , love that sound of channels coming together. Like first sound of the rebuild. Great video keep up the good work much apricated. Paddy.

AAAAHHH!! It sort of makes more sense to me now after listening to your thoughts out loud, why they used to call them ‘condensers’. THANKS FOR SHARING THIS!! I can really appreciate not just the cool looking aesthetics of your tester / LCR and other fancy tools, but also just hearing you speak out loud about the processes that you have seemingly gone through before. I’ll likely never forget your spool of wire that you’re using as a variable choke/coil, by clipping your lead at different points along the spool of wire. A+ content, and damned well worth the while. Thanks again!

That radio sounds fantastic and has great reception considering of how all of the old wax paper capacitors are still installed.

Next video: measuring the capacitance of cigarette residue (cigarette paste) on vintage electronics.

Never heard a radio make those funky sounds! Good Lesson!

I just worked it out, the yellow nail varnish was given to you when you had that meeting with Glasslinger!

Never thought I hear those radio noises outside of a cartoon. 📻

Beautiful radio, Shango! Love the copper & purple. Happy New Year to you!

The natural light really makes a difference! Interesting video.

Brilliant what you did with those mica caps. For tuning up my IF cans I use plastic knitting needles shaped to what shape I need. Take care. Terry

Very interesting. I've learned a lot. Thrilling to see it working good. have a couple radios I picked up about the same time as that RCA TV I showed you. Will send photos. Merry Christmas!

Cool vid. Yep, that (SMD) is becoming more noticeable these days especially. Good to see more vid's showing this and how to manage it. Thanks for posting.

This is perfect for the construction worker who cant whisle at the passing women.

Much better method with those series 119 cans is to use some small nippers (Xcelite) and cut the rivet off from the top. I've done about 100 of these and have got it down to 30 minutes for both, in out and back in again. Use your LCR meter to measure the inductance to figure out your cap values. Much easier than what you went through.

Great stuff! I am tired of all the magic cap replacement videos where the radio works better than new. Real troubleshooting is the way to go. Your videos are not professional but informative. That is the bottom line. Keep the good stuff coming!

for some reason, i really like the way that ugly purple radio looks...

I'm surprised those old electrolytics are working so good.

34:00 Low Fi punk rock... LOL. Uh, I think you made a theramin. HAHA. GREAT video as always, shango66 . Thanks for the tour of silver Mica issues.

Thanks for doing it this way, got a radio here I still need to figure out values for, had all kinds of crazy noises, figured I might have messed up somewhere, while that still may be true, the video parts without the caps, the squealing and motorboating etc were sure familiar. I'll have to dig back into it. Pretty much identical cans.

It was pretty cool watching the process of tuning the IF and hearing it dramatically improve by the end. Also interesting, the clock worked for a couple seconds starting at 31:45

I've started on a stack of postwar Zenith's and Philco's, most Bakelight, and you are quite correct, time and dendritic deposition is a One Hundred Percent Death Sentence for otherwise well-working radios, it'll be my contribution to getting thru these days without going nutz.

Who is giving thumbs down on these videos? These are the best educational videos on vintage electronics!

Ha, you and the antenna made a nice variable unit, could almost play it as an instrument!

Voltou a ficar novo! Rio Brasil

You are excellent, thankyou for the lesson.

For a minute there I thought you were successfully tuning in some other galaxy. If that was the case, then that radio far outperforms those monster sized dish antennas looking for ET's signal!

great job again MERRY CHRISTMAS

Always heard about SMD but now I see and understand. Nothing like a good visual.

Good video, nice repair & save of a decent radio. CBS used to make broadcast equipment, we found some old time base correctors that were made by CBS.

Great video thanks from England 🇬🇧

The inside of this radio looks similar to my old tube radio. I still love the purple & MERRY CHRISTMAS Shango. Xx

Your good The clock motor can be drilled open and a shot of WD-40 put into it, I"ve done that many times

What a great looking radio!

at 31:45 the clock started to work. anyone else notice that?

Great video Shango!!!!!

Wow the warmth and fuzzy analog AM audio. Audiophiles will pay big money for this. :)

nothing like listening to analog radio..... just a few of us guys left....

Shango you just built a theremin!

Nice..Nostalgic...I can feel that smell...and what a surprise that Korean broadcasting signal!

That speaker sounds good man

These videos are addictive, I don't know why ..I haven't a clue what he's talking about 😒😯😶🐲 theramin !!

Wow epic cluster of components globbed together. Amazing this stuff worked back then, I guess the lower frequency ranges were much more forgiving for 1950s glob construction.

Excellent video thanks!

Without the IF caps, it's motorboating and 'Thermin-ing'! I bet KNX comes in strong enough on a crystal set to drive a small speaker (or even a small car!).

Good repair, Quite like this radio.

In general, a very cool review of the receiver turned out for you!👍💪 In addition, an overview of broadcast AM stations in the MW medium wave range! In Russia, broadcasting in the MW band is completely ruined ,since since 2010 a decree of the president of the Russian Federation was signed to reduce the cost of broadcasting, in this regard, we have completely broadcast radio stations from Russia in Russian in the MW and SW bands throughout Russia.previously, there were many good and interesting programs in russian from america and europe ,but this was called propaganda)) I am very happy that in America radio broadcasting on medium and short waves is still relevant and a lot of radio stations both music and news broadcast as well as prnzhde 70 years ago ))

nice work ty!! don't stop!!

Cool! you made a theramin ! Beautiful radio. You should sell the stuff you fix on ebay... make a few $$ with your captive audience.

At 18:42 are we entering our destination time into the DeLorean? Another great video Shango!

Why not cut the little arms through the plastic. Use a Dremel. 4 cuts. Thin cutting bit, cuts the metal arms right off, through the plastic. No wasting time to disassemble rivet and lower base. Disable the arms, leave the mica inside, it's not going to do anything. Reinstall the can on the chassis,. Add the spec caps on the lugs under the chassis. Done. Specs should be on the diagram, if not start with 100pf each. You can add or subtract if necessary, and no need to remove the can any more. Done many many like that, even cans with 3 caps inside. 2 fixed, and the third output filter. Takes me about 15-20 min to do one complete. You may want to try that way one time. Take care sir.

Great video! Does the clock have a Telechron movement (that uses a sealed rotor)? The lubrication in the rotor has probably thickened up. If you pull the rotor and heat it up on a 75-100w light bulb, you can extract some of the old oil from around the gear shaft, and as it cools down, suck new oil into it (repeating a few times until it stops taking in oil). Considering the age, it probably uses an H-3 rotor (newer 60s sets would have S-1/S-7 rotors). I've been coming across SMD more and more in just the last 5 years or so. Really becoming a problem with a lot of these little sets. I have a couple radios that have recently (within a year or 2 sitting idle) developed it as well.

Concerning the two peaks: I think this trimmer affects the oscillator frequency and so you either send the difference or the sum of the oscillator and the input frequency into the IF filter chain. I might be horribly wrong about this though...

Time must of been slow, been 9:00 forever. Haha & it was cool to hear "The Greatest" by Sia, who by the way is Aussie like me. 😀

I live five miles from KNX and on my 1946 radio, I get a San Diego station Between KNX and Radio Disney. .

yeah!! shango meu amigo, olha você é um ótimo técnico de rádio & televisão, por outro lado, eu adoro os seus vídeos Gostei de ver o Radio antigo funcionamento muito bem yeah!! shango my friend, look you are a great radio & television technician, on the other hand, i love your videos I enjoyed seeing the old Radio working very well

+shango066 I'm so glad I found your channel, I love seeing old technology being brought back to life. The suggestion about the clock motor someone else posted was a good one. Drill a tiny hole in the motor casing and spray a bit of WD-40 into the case and manually turn the hands to set it to help work the fluid into the bearings. Are you going to give the face a clean up?

Should the capacitors be 47pf or 50pf for 455khz.

Shango couldnt you soak it in white spirit or similar?

I get a kick out of his finger poking everything...a highly sensitive, experienced chopstick.

can I replace a 35 volt 3uf capacitor with a 33uf or 1uf capacitor?

please use a tripod and/or panning slower. Do you have a video on using that LCR bridge. Good Video

Does this help you with your tinnitus?

There where some numbers stenciled on the metal frame. “26 1 5” Could this be its manufacture date?

Theese cans were 10$ a dozen we used to just put in new . back when people fixed this stuff.

just curious why not use a vtvm?

This video confuses me...how did you fix it?

What takes thw plastice of the wafer u removed

12:50 if it were my radio, I'd have left it without the IF caps, I always liked the tuning sounds old radios could make.

merry Christmas

4 Arco trimmers to expensive for that POS. Good work Shango. Are Arco's still even made or were those NOS?

That works very well, Very Very well.

Greetings! On 4:55 you mentioned that the leads were loose. Can't you put crazy glue to in between the leg of the leads and the plastic where the leads come out? This should prevent the legs from moving and breaking the fine wire.

Is that transformer ,replaceable ,or,do you have to rebuild it

this radio and my truck tape deck player same!

clock moves at 31:45

Not bad a'tall 'go, if you get the clock to work, it would be the cat's meow for sure, make for a nice kissymas gift from ShangoKlauz. Happy holidays and season's greetings, um being PC. The Donold

16:20 Dazzlin' Dan's Amazing Theremin! 🤣

did you confirm the disc stated values with the cap tester? that is if you used the printed value on the cap. Just curious if maybe the stated value was different from the actual values.

what happens when you remove the mica wafer? what's its purpose? insulator?

Why not select the capacitor when the filter can is outside the radio with a scope and frequency generator? Yea the peak frequency will change slightly when you put the filter back in circuit, but you could finetune that with the core of the coil.

Did you not put a matching value capacitor to replace the mica caps.?

Does it matter which I-F can you align first?

I can't find part 1

Wow, that was tedious work! So, what are the ill-effects of removing the silver mica from the cans? Why are they there in the first place?

Is this common in 30s, 40,s 50s radios? Or is it specific to a certain decade?

Why is it necessary to remove the mica wafer? Also, what about all those horrible old wax capacitors that are likely passing DC and tearing up the tubes?

Nice repair, good selectivity in the end. I mainly deal with Japanese tube radios, all of the IFT's I have whose datasheet specifies the capacitor value list them at 100pf, so far i've never had to use any other value but a variable capacitor would be the way i'd do it too if I couldnt get a good response by using a 100pf. I guess by peaking the response at 455 with a capacitor and leaving the slug alone would give the best capacitor value based on the current position of the slug, which may have not already been in the optimium position, if say the IFT's originally had say a 100pf capacitor. Perhaps if you set all those capacitors to 100pf and tried peaking the slugs for maximum response you'd probably have ended up with the same over all sensitivity, if so then your original slug position might have benefitted from a little tweaking too if they hadn't died of mica disease. I don't have many US radios but that CBS radio sure does look a lot like my Philco 49-905, minus the FM, did CBS make their own radios or were they rebadged from another manufacturer?

Hi! It has been my experience that 100 pf caps across the board and then peaking the IF's with the slugs. Usually works. Brendan

Greetings: For next time, replace 1 if trim cap at a time tuning for max if modulation level.

Fix the Clock?

Too bad you don't do clocks -- LOL Nice video!

Whenever you gain anything by recapping up the radio in the clock radio any better than it is right now or if I just going to be it's good as it gets

this is sound poetry~
